Research Methodology

TheStreet Ratings condenses the available fund performance and risk data into a single composite opinion of each fund's risk-adjusted performance. This allows the unbiased identification of those funds that have historically done well and those that have underperformed the market. While there is no guarantee of future performance, these investment ratings provide a solid framework for making informed, timely investment decisions. In order to qualify for a rating, an open-end fund must either have three years of risk and return data or be an additional share class of an existing fund with at least three years of performance statistics.

Funds rated "A" or "B" are considered "Buy" based on a track record of higher than average risk-adjusted performance. Funds at the "C" level are rated as "Hold," while underperformers at the "D" and "E" levels our model ranks as "Sell."
